Mr. Vince Burlapp and his The Hollywood Extra Car Page brings us another mystery. This time it is a completely random image of what looks to be a Mazda6/Atenza coupe sketch. Burlapp claims this is a sketch from Mazda, so we'll go with that for now. It would make sense to us to bring a Mazda6 coupe to the world as all the competition seems to be doing it and Mazda has had an unfortunate excess of doors recently. Here are some pictures of the Mazdaspeed Atenza Concept, which seem to share similar touches.
